Lactococcus lactis mutants resistant to lactococcin A and garvicin Q reveal missense mutations in the sugar transport domain of the mannose phosphotransferase system

open access: yesMicrobiology Spectrum
Lactococcin A is a bacteriocin from Lactococcus lactis that permeabilizes the membrane of sensitive lactococcal cells and requires the presence of the membrane-bound components IIC and IID of the mannose phosphotransferase system (man-PTS).

Assessment of the Functional Regions of the Superantigen Staphylococcal Enterotoxin B

open access: yesToxins, 2013
The functional activity of superantigens is based on capacity of these microbial proteins to bind to both the β-chain of the T cell receptor (TcR) and the major histocompatibility complex (MHC) class II dimer.

HSEARCH: fast and accurate protein sequence motif search and clustering [PDF]

open access: yesarXiv, 2017
Protein motifs are conserved fragments occurred frequently in protein sequences. They have significant functions, such as active site of an enzyme. Search and clustering protein sequence motifs are computational intensive. Most existing methods are not fast enough to analyze large data sets for motif finding or achieve low accuracy for motif clustering.

Expression and purification of soluble and active human enterokinase light chain in Escherichia coli

open access: yesBiotechnology Reports, 2021
Human enterokinase light chain (hEKL) specifically cleaves the sequence (Asp)4-Lys↓X (D4K), making this a frequently used enzyme for site-specific cleavage of recombinant fusion proteins.

Protein Hypernetworks: a Logic Framework for Interaction Dependencies and Perturbation Effects in Protein Networks [PDF]

open access: yesarXiv, 2011
Motivation: Protein interactions are fundamental building blocks of biochemical reaction systems underlying cellular functions. The complexity and functionality of such systems emerge not from the protein interactions themselves but from the dependencies between these interactions.

Immunological responses in the mouse host to a cloned antigen of Taeniacrassiceps [PDF]

open access: yes, 1996
Adult female Swiss-Webster mice were immunized either intraperitoneally (IP) or subcutaneously (SQ) with cyst fluid or a genetically engineered fusion protein, Taenia carassiceps antigen 2-maltose binding protein (TCA2-MBP) from Taenia crassiceps ...

Frizzled Proteins are bona fide G Protein-Coupled Receptors [PDF]

open access: yes, 2009
Receptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling multiple steps in organism development and highly conserved in evolution. Misactivation of the Wnt/Frizzled signaling is cancerogenic.
